Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pixel units in display technology suffer from color deviation when viewed from different angles due to uniform slit electrode incline directions, which affects light transmittance.
Innovation Solution
A pixel unit structure with four zones, where slit electrodes are electrically connected and have the same incline direction within each zone but differ between adjacent zones, arranged at the cross position of gate and data lines, ensuring mirror symmetry and uniform liquid crystal orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the slit incline directions of the slit electrodes in the pixel unit are made the same, then the light transmittance is increased, but a color deviation under left and right, upper and lower view angles is caused
Solution Approach 1:
The pixel unit is divided into four distinct zones (first, second, third, and fourth zones) with different slit incline directions. Each zone has its slit electrodes inclined at different angles relative to the gate line, creating multiple domains within a single pixel unit. This segmentation allows different regions to optimize for different viewing angles while collectively improving overall light transmittance.
Solution Approach 2:
Different zones within the pixel unit are assigned different local properties (slit incline directions). Specifically, the first zone has slit electrodes inclined at a first angle, the second zone at a second angle, the third zone at a third angle, and the fourth zone at a fourth angle. This local differentiation eliminates color deviation in various viewing directions while maintaining high light transmittance across the entire pixel unit.
2Ease of manufacture
If the pixel unit is arranged at a cross position of gate line and data line with four zones, then color deviation is eliminated to the greatest extent, but the structure complexity is increased
Solution Approach 1:
The pixel unit employs an asymmetric arrangement of slit electrodes in different zones, with each zone having distinct incline directions relative to the gate line. This asymmetric design, where slit electrodes are not uniformly oriented but rather distributed at different angles across four zones, effectively eliminates color deviation by compensating for viewing angle dependencies in different directions.
Solution Approach 2:
The invention introduces a new dimensional aspect to the pixel structure by dividing it into four spatial zones with different orientational characteristics. This multi-dimensional approach, where each zone contributes differently to light transmission from various angles, transforms a simple uniform structure into a complex multi-domain structure that addresses color deviation comprehensively.
